FLUID SE Application filed September This invention relates to a device for the automatic isolation of fluids, but more particularly to a. device for straining and separating water and sediment from gasoline. The invention is applicable for the separation or isolationof any two fluids of different specific gravities which are non-miscuous, such as oil and water.

The invention has for its object to provide certain material improvements in the art such as the adjustability of the float to any desired degree of buoyancy to adapt the device for use in the separation and isolation of various fluids which differ in specific Y gravity.

Afurther object of the invention is to provide means for obviating the eflect of vibration between the float and the needle valve so that the device will properly function under the usual conditions of service. v

With these and other objects in view, the invention consists of the construction, arrangement and combinations of pa rts,'all of which will be first fully described and afterwards specifically pointed out in the append- Referring to the accompanying drawings:

plug is removed and a pipe or tube (not shown) is connected to said passage and leads to a carburetter or the like.

7 indicates the float chamber which may be of any suitable material, but which is shown of glass in the accompanying drawings. This chamber is conventionally shaped and has its upper edge slightly flared at 8 1 to be received by the clamping ring 9 against a suitable packing gasket 10, disposed under the flange 11 of the top casting. This assembly is effected by the screws 12 as shown in Figures 1v and 2.

The bottom 13 of the float chamber is apertured to receive the upstanding tubular valvestem guide 14, which as shown in Figure 2, is provided with .a threaded nipple-end 15 which is passed through thebottom 13 of the float chamber, said threaded end of the said -guide also including a flange 16 under which is disposed a suitable packing gasket-17 to eflecta fluid tight joint. The said threaded end of the said guideis Internally threaded to I receive the centrally bored valve seat 18..' Inclosing, the threaded nipple-end ,15, is a retainingfnut 19acting against a suitable packing gasket 20 by means of which retaining nut 19 this assembly is effected. Threaded in the bottom of said retaining nut 19 is a drain valve 21 which includes an upper flanged'head 22 and a cen: tralbore 23, in communication with which bore is a. drain port 24 through the wall of the valve 21. A wing nut 25is secured to y the bottom end of the valve 21, by means of 3 which, rotation is imparted to saidvalve to raise or lower the flanged head 22 and to '-ra-ise and lower the drain port24 into and out of communication with the chamber formed by the threaded nipple-end 15.

26 indi cates a: long tubular screen located in the side of the float chamber and connected,

as shown in Fig. 2 to the discharge end of the.

deflector 4 which tubular screen receives all fluids and sediment passing into the device..

27 indicates the float which is provided with a central tube 28 bymeans of which, said float is'slidably mounted on the upstanding. tubular valve-stem guide 14 heretofore described.

Resiliently and flexibly connected to the float 27 is the stem 29 of the needle valve 30, so that said valve is seated and unseated by the float 27 which connection is effected by the springs 31 as shown in Figs. 1 and 2.

Arranged in the bottom of the float'is a series of stand pipes 32 of varying lengths (Fig. 2) which are arranged in pairs of the same length as shown in Fig. 2. Disposed under said series of stand pipes is a washer 33 and a. lock washer 34, the same being provided with one pair of perforations 35' which may be brought in position to register with any one pair of said stand pipes 32 or to cover all the said stand pipes 32.

Disposed under the passage 5 leading to the outlet passage 6 is a screen 36, while at the upper endof said passage 5 is a closed-end tube 37 having a series of narrow slots 38 therein near the top thereof, said slotted end of the tube 37 extending upwardly within and to one side of the-sieve 39 which is disposed overthe inlet passage 3, while the upstanding boss 40 of the top casting 2 isthreaded at 41 for connection with a pipe line, tank or other supplies.

Having thus described the component parts of this invention, its operation is as follows:

Fluid supplied to the device through a pipe or feedline tank or other supply (not shown) passes through the sieve 39 and thence into Passage 3 onto the deflector t and into the tubular sieve 26, thence into the float chamber ,7. In order to adapt the device to the isolation or separation of the particular non-miscuous fluids of different specific gravities to be handled, such as the isolation or separation of" water from gasoline, the buoyancy of the float 27 is adjustedas follows: The washer 33and lock washer 34 under the'float 27 are rotated until that pair of stand pipes which are of the-length previously determined for water, are uncovered, and the float is'inverted and thenimmersed in water and permitted to fill. The liquid enters one stand pi e and air escape through theother so that t e float fills up to the'inner ends of the stand pipes, but no further,

as the air remaining in the float is trapped in the float and precludes the further entry of water. It will thus be seen that the longer the stand pipe, the less the quantity of liquid can enter the float, so that by this means the float can be exactly and accurately weighted to adjust the relative buoyancy of the float, to the end that the buoyancy level B ismaintaincd at constant height, as diagrammatically'illustrated in Fig. 3. When the float has thus been filled, the washer 33 and lock washer 34 are again rotated to seal said stand v pipes 32. The float is then reversed and assembled in position shown in the drawings. In the diagrammatic views, the buoyancy level is indicated by B while O indicates the lighter component of the liquid such as gasoline, and D indicates the heavier comruptedflow of the lighter component such Fig. 4, however, illustrates a quantityof' the heavier component such as water entering the device and illustrates the operation of the deflector 4 which facilitates therapid sep-' aration of the two components. The lighter components in the float chamber being displaced by the heavier component entering the float chamber, passcout through the passage 5 and into the screen 39, in proportion to the uantity of theheavier component entering t )0 float chamber, for as the heavier com ponent enters the device, the lighter component already therein must be dis laced therefrom in the same proportion. uch flow of the liquid will continue by reason of the relativediameters of the inlet passage 3 andthe passage 5, as long as the heavier component continues to enter the float chamber. I have found by experiment that in the absence'of such an arrangementfor permitting displacement of the lighter component from the device as by the provision of passages 3 and 5, the sudden introduction of a large quantity of the heavier component would tend to accumulate'in the" inlet'passage' by reason of'the uplating. passage 5 is provided which permits and allows the displacement of the lighter component from the float chamber into the feed line and at a point above the inlet passage 3. This prevents and overcomes the tendency of a suddenly introduced large quantity of the heavier component to lodge in the inletpassage 3, by permitting such heavier componentto pass into the float chamber. The action is somewhat analogous to'that of a venting action. in that it provides for the displacement from' the float chamber of a quantity of the lighter component suflicient to permit the entrance of the heavier com ponent therein, since a quantity of the heavier component cannot he suddenly introduced float chamber upon the sudden introduction therein of a large quantity of the heavier ponentsuch as water which is separated and\ component.

In Fig. 3, the arrows'indicate the uninter- WVh'ile the incoming fluid may enter the circulating pipe 5 in very small quantity,the

ously interfere with the proper functioning a of ag-device of this class,

component enters the float chamber, it causes a rise'in the buoyancy level B, as from dotted lines in Fig. 5 to full lines in said figure. By reason of the relative buoyancy, the float is displaced upwardly as shown in said figure which raises the needle-valve and permits the escape of the heavier component through the drain 23. This discharge continues until i the buoyancy level B is restored, at which level the float has descended into position to reseat the needle-valve 30 and shut off further evacuation of the heavier component as shown in Fig. 6.- This action is automati-' cally repeated each time the quantity of the heavier component in the float chamber becomes suflicient to cause a rise in the buoyancy adjusting the buoyancy of said float, the

level.

and thereby obviate any direct or frictional contact between the said stem and the float, while the flexible or resilient spring connection em loyed, permits free vertical movethe float within the limits of the resiliency of the springs without imparting any movement tothe needle-valve. By,
